Warming up engine

EMU27717

Manual start and electric start models

1.

After starting the engine, allow it to idle
for 3 minutes to warm up. Failure to do
so will shorten engine life.

2.

Be sure the low oil pressure-alert indica-
tor goes off after starting the engine.

NOTICE:

If the low oil pressure-alert

indicator blinks after the engine starts,
stop the engine. Otherwise, serious
engine damage could occur. Check
the oil level and add engine oil if nec-
essary. Consult your Yamaha dealer if
the cause for the low oil pressure alert
cannot be found.

Checks after engine warm up

EMU36542

Shifting

While the boat is tightly moored, and without
applying throttle, confirm that the engine
shifts smoothly into forward and reverse, and
back to neutral.

EMU36981

Stop switches



Turn the main switch to “

”, or press the

engine stop button and make sure the en-
gine stops.



Confirm that removing the clip from the en-
gine shut-off switch stops the engine.



Confirm that the engine cannot be started
with the clip removed from the engine shut-
off switch.

EMU34531

Shifting

WARNING

EWM00181

Before shifting, make sure there are no
swimmers or obstacles in the water near
you.

NOTICE

ECM01611

Warm up the engine before shifting into
gear. Until the engine is warm, the idle
speed may be higher than normal. High
idle speed can prevent you from shifting
back to neutral. If this occurs, stop the en-
gine, shift to neutral, then restart the en-
gine and allow it to warm up.

To shift out of neutral
1.

Pull the neutral interlock trigger up (if
equipped).

2.

Move the remote control lever / gear shift
lever firmly and crisply forward (for for-
ward gear) or backward (for reverse gear)
[about 35° (a detent can felt) for remote
control models]. Be sure to check that
the tilt lock lever is in the lock/down po-
sition (if equipped) before operating in re-
verse.

1. Neutral interlock trigger
